The Pros: Shrimp is packed with protein and it's DELICIOUS. It is also a good source of vitamin B12 and has less sodium than crab and lobster. And shrimp is loaded with vitamin D, making it a good option in the winter when we don't get a lot of sunshine (a big source of said vitamin). You can get it precooked or raw, with shells or without, small or jumbo, etc. And prices on frozen shrimp are usually pretty reasonable. Plus, frozen shrimp can be quickly thawed, making it ideal for a last-minute meal. And it's good in just about everything (except dessert).

The Cons: Cholesterol-conscious types might want to steer clear of shrimp. Despite being low in fat, it is high in cholesterol. There is, however, evidence suggesting that shrimp could be effective in raising "good" cholesterol. Click here for more on that...

The Pros:
Crab is full of protein, low in fat, and a good source of minerals (like copper, for energy!). And like our other shellfish-y friends, it's got those omega-3s and vitamins. It's also SUPER-VERSATILE. The canned kind is great to keep on hand in the pantry -- we're big fans of Chicken of the Sea Lump Crab. Convenient and tasty. Woohoo!

The Cons:Actual crab legs can be expensive and are really high in sodium; plus, it takes a whole lot of work to get to just a little bit of meat! And finding decent packaged crabmeat can be tricky -- some kinds smell funky and others just don't taste good. Heads up: If you like imitation crab better (some people do; don't judge!), click here for some info on that stuff.

The Pros:
It's REALLY delicious. It also happens to be nice and low in calories and fat. Lobster contains zinc, potassium, healthy omega-3 fatty acids, and vitamin B12. Wowsers. And at restaurants, it's often available broiled or steamed, prepared without any oil. YES!!!!

The Cons:
It's expensive. That's the reason none of our recipes below include lobster. Plus, it's a bit high in sodium. And while it's often served plain, it's also notoriously paired with fattening ingredients like melted butter, creamy sauces, and mounds of pasta.
